    Multimodal mismatch responses in mouse auditory cortex by Magdalena Solyga, Georg B Keller

    Published 2025-02-01
    “…To investigate multimodal prediction errors in mouse auditory cortex, we used a virtual environment to experimentally couple running to both self-generated auditory and visual feedback. Using two-photon microscopy, we first characterized responses of layer 2/3 (L2/3) neurons to sounds, visual stimuli, and running onsets and found responses to all three stimuli. …”

    Wet-Chemical Surface Texturing of Sputter-Deposited ZnO:Al Films as Front Electrode for Thin-Film Silicon Solar Cells by Xia Yan, Selvaraj Venkataraj, Armin G. Aberle

    Published 2015-01-01
    “…Transparent conductive oxides (TCOs) play a major role as the front electrodes of thin-film silicon (Si) solar cells, as they can provide optical scattering and hence improved photon absorption inside the devices. In this paper we report on the surface texturing of aluminium-doped zinc oxide (ZnO:Al or AZO) films for improved light trapping in thin-film Si solar cells. …”

    APOE4 and sedentary lifestyle synergistically impair neurovascular function in the visual cortex of awake mice by Silvia Anderle, Orla Bonnar, Joseph Henderson, Kira Shaw, Andre M. Chagas, Letitia McMullan, Alexandra Webber, Kirsty McGowan, Sarah L. King, Catherine N. Hall

    Published 2025-01-01
    “…Here, we ask whether genetic and lifestyle risk factors for AD—the ε4 allele of the Apolipoprotein (APOE) gene, and physical activity—can together produce this reduction in cerebral blood flow which leads eventually to AD. Using in vivo two-photon microscopy and haemodynamic measures, we record neurovascular function from the visual cortex of physically active or sedentary mice expressing APOE3 and APOE4 in place of murine APOE. …”
